Some insight on my build

I already have the heads should i gasket match and clean em up or otb ? And what about a 373s gear.
If your not afraid to do this yourself, go for it.
On gasket matching, don’t worry about the ports floor to much. Ceiling and walls are most important. Run the porting work as far up into the port until the intake and/or head walls start to move away from the dimensions of the gasket shape. Remember, you don’t have to go nuts on it.
Not sure how much i would want to be leaning on a 70 over 360 block. If you plan on making anything even approaching serious power
Of course you wouldn’t. You would need to know how thick the cylinder wall was to start and finish with before you built it. If it was to think to harp on the engine in a drag race, you would t have gone there in the first place.

If it was bad to go there, you would have selected a different block. Saved the bad one for a people mover build at best.

What’s funny about your post is he lists the parts used for the build. I was wondering, do you consider that serious power that he should be afraid of that he gets the warning?
